Inductive generalization, where people go beyond the data provided, is a basic cognitive capability, and it underpins theoretical accounts of learning, categorization, and decision making. To complete the inductive leap needed for generalization, people must make a key ‘‘sampling’’ assumption about how the available data were generated. Previous models have considered two extreme possibilities, known as strong and weak sampling. In strong sampling, data are assumed to have been deliberately generated as positive examples of a concept, whereas (...) in weak sampling, data are assumed to have been generated without any restrictions. We develop a more general account of sampling that allows for an intermediate mixture of these two extremes, and we test its usefulness. In two experiments, we show that most people complete simple one-dimensional generalization tasks in a way that is consistent with their believing in some mixture of strong and weak sampling, but that there are large individual differences in the relative emphasis different people give to each type of sampling. We also show experimentally that the relative emphasis of the mixture is influenced by the structure of the available information. We discuss the psychological meaning of mixing strong and weak sampling, and possible extensions of our modeling approach to richer problems of inductive generalization. (shrink)

Common understandings of neuroethics, i.e., of its distinctive nature, are premised on two distinct sets of claims: (1) neuroscience can change views about the nature of ethics itself and neuroethics is dedicated to reaping such an understanding of ethics; (2) neuroscience poses challenges distinct from other areas of medicine and science and neuroethics tackles those issues. Critiques have rightfully challenged both claims, stressing how the first may lead to problematic forms of reductionism while the second relies on debatable assumptions (...) about the nature of bioethics specialization and development. Informed by philosophical pragmatism and our experience in neuroethics, we argue that these claims are ill-founded and should give way to pragmatist reconstructions. Namely, neuroscience, much like other areas of empirical research on morality, can provide useful information about the nature of morally problematic situations but it does not need to promise radical and sweeping changes to ethics based on neuroscientism. Furthermore, the rationale for the development of neuroethics as a specialized field need not to be premised on the distinctive nature of the issues it tackles or of neurotechnologies. Rather, it can espouse an understanding of neuroethics as both a scholarly and a practical endeavor dedicated to resolving a series of problematic situations raised by neurological and psychiatric conditions.

In lieu of an abstract, here is a brief excerpt of the content:846 BOOK REVIEWS Marx's Socwl Critique of Culture. By Loms DUPRE. New Haven: Yale University Press, 1983. Pp. ix + 299. $30.00 (cloth) and $9.95 (paper). Modernity has produced in equal measure material abundance and critical disdain. Its critics may he roughly divided into two groups. Negative critics deny all value to modernity and long for a glorious past or a perfect future; the romanticism of an Othmar Spann (...) or the utopian anarchism of a Mikhail Bakunin provide excellent examples of this type. Of more interest to political theory, however, are the dialectical critics who both affirm and deny the modern project; Rousseau and Marx are the greatest thinkers in this category. Louis Dupre is certainly a critic of modernity. The nature of his complaint remains to he determined. I should begin by saying that Dupre's hook neither condemns nor worships Marx. From the start he sets for himself the unfashionable task of understanding his author before passing judgment on his ideas. Hence, Dupre explicitly distinguishes interpretation from critique and devotes most of this hook to elucidating Marx's ideas. Some readers would perhaps agree with Hahermas that interpretation is always critique, hut I find that Dupre generally maintains this distinction in these pages. I turn first to his reading of Marx. This is not a hook about what might he called high culture, a civilization 's achievements in expressing the human spirit. Dupre relies little on Marx and Engel's scattered reflections on art and society, and he spends relatively few pages on the Frankfurt School and their critique of contemporary popular culture. Dupre is rather a philosopher using Marx to think about culture in a fundamental way. His subject is modernity itself and particularly Marx's criticism of the essentially modern separation of culture and activity. The first part of the hook focuses on Marx's conception of alienation. For almost half a century questions about the unity of Marx's early and late writings have accompanied explications of Entfremdung. Dupre sides with those who see a unity of purpose in the works of the young and the old Marx. Although the idea of alienation appears rarely in Das Kapital, Dupre argues that Marx continually attacked bourgeois society for separating subject and object. Culture thus becomes in capitalist societies an object of exchange value that stands in opposition to its producers, a commodity like all others. The second chapter pursues Marx's belief that alienation must he understood socially and historically. Here Dupre provides a subtle interpretation of Marx's conceptions of base and superstructure. He concludes that Marx rejected the logical extremes of determinism and voluntarism BOOK REVIEWS 847 in history. Instead, the rational will of the proletariat was viewed as the culmination of social development. Yet, as Dupre notes, Marx's belief in the general principle that history is progressive turns on his specific analysis of the spread of capitalism; the generalization about history depends in the end on unproven assumptions about the development of capitalism. Dupre devotes his third chapter to a broad and learned discussion of the role of the dialectic in Marx and Marxist political theory. Marx himself did not provide a complete and clear account of dialectical contradiction; any tension that might lead to the destruction of capitalism fell within Marx's understanding of contradiction. Dupre's conclusion that Marx ultimately founded his dialectical method on an undefended teleology will, I think, ring true to most students of the subject. His discussion of the realist interpretation of the dialectic will occasion controversy largely because Dupre believes Engel's methodological ideas in Anti-Dukring can he legitimately associated with Marx's views. This is an important and damning link, for, of course, the scientism enunciated in Anti-Dukring took Marxism a long way toward both the relatively benign orthodoxy of the German Social Democrats and the horrible monism of Stalin. For Marx, however, the dialectic was more than anything else a way of positing the loss of social and culture unity and of foreseeing their reintegration. His exposition of Marx's atempt to unify economic and social activity contains a thoughtful reconstruction of the concept of value in classical economics... (shrink)

To date researchers planning experiments have always lived by the mantra that 'using equal sample sizes gives the best results' and although unequal groups are also used in experimentation, it is not the preferred method of many and indeed actively discouraged in literature. However, during live study planning there are other considerations that we must take into account such as availability of study participants, statistical power and, indeed, the cost of the study. These can all make allocating equal sample sizes (...) difficult, and sometimes near impossible. This, some might say, means that the study would not adhere to rigorous statistical standard (Rosenbaum and Rubin, 1985). However, here we present evidence that, not only is this a false assumption, but that we may actually gain more power in the study by actually using unequal groups. Here, data from a Sepsis Biomarker study is used, in which the aim is to predict, by biomarker level and presence, whether the patient would go on to develop sepsis. It was found that larger control groups may give more power to studies looking for an effect in the mid range but not for large or small effects. This study shows merit in the hypothesis that more power can be achieved when a larger control group is used.

To achieve more cost-effective deterrence of unreasonable risktaking through civil liability, I propose and demonstrate previously unrecognized benefits of using simple random sampling to resolve multiple claims against a business or government defendant in the aggregate. I show that counter to intuition and prevailing assumptions and practice, simple sampling will enhance, not compromise, deterrent results regardless of the number of claims and the variety and significance of differences among them. Indeed, it can be used to resolve multiple (...) claims that bear no resemblance to one another except for targeting the same defendant. The proposal can thus be employed to increase the efficiency of resolving relatively similar claims in class and consolidated actions and, by extending the application of such collectivizing processes, lower the cost of resolving all other claims that would be adjudicated as separate actions. I close by sketching a design for a reformed civil liability system that fully integrates and exploits the law enforcement benefits of sampling to better achieve the primary social objectives of accident risk deterrence and insurance.

The ability to exchange samples and data is crucial for the rapidly growth of biobanking. However, sharing is based on the assumption that the donor has given consent to a given use of her or his sample. Biobanking stakeholders, therefore, must choose 1 of 3 options: obtain general consent enabling multiple future uses before taking a sample from the donor, try to obtain consent again before sharing a previously obtained sample, or look for a legally endorsed way to share a (...) sample without the donor's consent. In this study, we present the results of 36 semistructured qualitative interviews with Swiss biobanking stakeholders regarding these options and the role of ethics committees in the process of authorizing sharing. Our results show that despite a lack of legal or guideline-based barriers to general consent, some stakeholders and ethics committees have reservations about this method of consent. In most cases, however, a general consent form is already in use. Many interviewees describe processes involving the ethics committees as time-consuming and cumbersome and their requirements as too demanding for donors/patients. Greater awareness of donors' opinions and preferences and the content of guidelines and recommendations could therefore be helpful for a better justified perspective of biobanking stakeholders and ethical committee members, equally. Finally, it may be necessary to differentiate between procedures governing future samples, where general consent is clearly desirable, and the use of old yet still relevant samples, where the option of using them without consent can be highly beneficial for research.

Fisher criticised the Neyman-Pearson approach to hypothesis testing by arguing that it relies on the assumption of “repeated sampling from the same population.” The present article considers the responses to this criticism provided by Pearson and Neyman. Pearson interpreted alpha levels in relation to imaginary replications of the original test. This interpretation is appropriate when test users are sure that their replications will be equivalent to one another. However, by definition, scientific researchers do not possess sufficient knowledge about the (...) relevant and irrelevant aspects of their tests and populations to be sure that their replications will be equivalent to one another. Pearson also interpreted the alpha level as a personal rule that guides researchers’ behavior during hypothesis testing. However, this interpretation fails to acknowledge that the same researcher may use different alpha levels in different testing situations. Addressing this problem, Neyman proposed that the average alpha level adopted by a particular researcher can be viewed as an indicator of that researcher’s typical Type I error rate. Researchers’ average alpha levels may be informative from a metascientific perspective. However, they are not useful from a scientific perspective. Scientists are more concerned with the error rates of specific tests of specific hypotheses, rather than the error rates of their colleagues. It is concluded that neither Neyman nor Pearson adequately rebutted Fisher’s “repeated sampling” criticism. Fisher’s significance testing approach is briefly considered as an alternative to the Neyman-Pearson approach. (shrink)

In many learning or inference tasks human behavior approximates that of a Bayesian ideal observer, suggesting that, at some level, cognition can be described as Bayesian inference. However, a number of findings have highlighted an intriguing mismatch between human behavior and standard assumptions about optimality: People often appear to make decisions based on just one or a few samples from the appropriate posterior probability distribution, rather than using the full distribution. Although sampling-based approximations are a common way to (...) implement Bayesian inference, the very limited numbers of samples often used by humans seem insufficient to approximate the required probability distributions very accurately. Here, we consider this discrepancy in the broader framework of statistical decision theory, and ask: If people are making decisions based on samples—but as samples are costly—how many samples should people use to optimize their total expected or worst-case reward over a large number of decisions? We find that under reasonable assumptions about the time costs of sampling, making many quick but locally suboptimal decisions based on very few samples may be the globally optimal strategy over long periods. These results help to reconcile a large body of work showing sampling-based or probability matching behavior with the hypothesis that human cognition can be understood in Bayesian terms, and they suggest promising future directions for studies of resource-constrained cognition.

Humans can seamlessly infer other people's preferences, based on what they do. Broadly, two types of accounts have been proposed to explain different aspects of this ability. The first account focuses on spatial information: Agents' efficient navigation in space reveals what they like. The second account focuses on statistical information: Uncommon choices reveal stronger preferences. Together, these two lines of research suggest that we have two distinct capacities for inferring preferences. Here we propose that this is not the case, and (...) that spatial-based and statistical-based preference inferences can be explained by the assumption that agents are efficient alone. We show that people's sensitivity to spatial and statistical information when they infer preferences is best predicted by a computational model of the principle of efficiency, and that this model outperforms dual-system models, even when the latter are fit to participant judgments. Our results suggest that, as adults, a unified understanding of agency under the principle of efficiency underlies our ability to infer preferences. (shrink)

Major depression (MD) is a highly heterogeneous diagnostic category. Diverse symptoms such as sad mood, anhedonia, and fatigue are routinely added to an unweighted sum-score, and cutoffs are used to distinguish between depressed participants and healthy controls. Researchers then investigate outcome variables like MD risk factors, biomarkers, and treatment response in such samples. These practices presuppose that (1) depression is a discrete condition, and that (2) symptoms are interchangeable indicators of this latent disorder. Here I review these two assumptions, (...) elucidate their historical roots, show how deeply engrained they are in psychological and psychiatric research, and document that they contrast with evidence. Depression is not a consistent syndrome with clearly demarcated boundaries, and depression symptoms are not interchangeable indicators of an underlying disorder. Current research practices lump individuals with very different problems into one category, which has contributed to the remarkably slow progress in key research domains such as the development of efficacious antidepressants or the identification of biomarkers for depression. The recently proposed network framework offers an alternative to the problematic assumptions. MD is not understood as a distinct condition, but as heterogeneous symptom cluster that substantially overlaps with other syndromes such as anxiety disorders. MD is not framed as an underlying disease with a number of equivalent indicators, but as a network of symptoms that have direct causal influence on each other: insomnia can cause fatigue which then triggers concentration and psychomotor problems. This approach offers new opportunities for constructing an empirically based classification system and has broad implications for future research. (shrink)

The self-indication assumption (SIA) claims that given that one exists, one should think that the universe has many people, for a universe that has more people is more likely to contain any particular person. SIA is attractive to many because it diffuses the infamous doomsday argument, and avoids the problems of its main rival, the self-sampling assumption (SSA), which instructs one to reason as if they’re randomly selected from the people in their reference class. Here, I will go further (...) than the traditional argument for SIA from its ability to avoid the doomsday argument: I will show that any view other than SIA must accept the soundness of the doomsday argument and certain even stranger conclusions. Additionally, I’ll argue that the main objection to SIA, the presumptuous philosopher case, is unconvincing. Together then, these considerations give one a strong reason to adopt SIA. (shrink)

The moral foundations theory (MFT) proposes that there are five moral foundations that work as the standard to make moral judgments. Among them, the purity foundation is a complex concept. It is considered to be a distinctive foundation compared with the other ones partly because it involves religious beliefs. The assumption underlying the purity foundation is Christian beliefs, so the MFT was developed and made prevalent mostly in the Western cultures. However, because of that assumption, cultural differences in perceiving the (...) purity foundation should be observed with a non-Western sample, such as Japan. It would be important to discuss and clarify the Japanese unique aspect of their orientation toward the pure and impure. We constituted a scale to measure people's tendency toward purity orientation–pollution avoidance (POPA), based on the purity/sanctity subscale of the MFT. For validation, we administered several scales along with POPA. In Study 1, we developed the scale and measured the relationship between the degree of one's POPA, disgust, and animism. We identified four factors as POPA subscales. In Study 2, we investigated the test–retest reliability of POPA and conducted questionnaire surveys to measure attitudes toward paranormal phenomena and the degree of concern for each of the moral foundations. The results showed the validity of the scale, based on the moderate correlations with other scales. The POPA can be a promising tool to better understand the phenomena involving the purity foundation in a Japanese context. (shrink)

Most current theoretical models of dreaming are built around an assumption that dream reports collected on awakening provide unbiased sampling of previous cognitive activity during sleep. However, such data are retrospective, requiring the recall of previous mental events from sleep on awakening. Thus, it is possible that dreaming occurs throughout sleep and differences in subsequent dream reports are owing to systematic differences in our ability to recall mentation on awakening. For this reason, it cannot be concluded with certainty that (...) sleep cognition is more predominant or in any way different during REM compared to NREM sleep. It is our contention that REM sleep and ponto-geniculo-occipital (PGO) waves do not necessarily represent stimulation of the cortex in the generation of dreams, but might rather represent enhanced arousal of attention mechanisms during sleep, which results in the subsequent recall of attended mentation on awakening.

“Decisions from experience” (DFE) refers to a body of work that emerged in research on behavioral decision making over the last decade. One of the major experimental paradigms employed to study experienced-based choice is the “sampling paradigm”, which serves as a model of decision making under limited knowledge about the statistical structure of the world. In this paradigm respondents are presented with two payoff distributions, which, in contrast to standard approaches in behavioral economics, are specified not in terms of (...) explicit outcome-probability information, but by the opportunity to sample outcomes from each distribution without economic consequences. Participants are encouraged to explore the distributions until they feel confident enough to decide from which they would prefer to draw from in a final trial involving real monetary payoffs. One commonly employed measure to characterize the behavior of participants in the sampling paradigm is the sample size, that is, the number of outcome draws which participants choose to obtain from each distribution prior to terminating sampling. A natural question that arises in this context concerns the “optimal” sample size, which could be used as a normative benchmark to evaluate human sampling behavior in DFE. In this theoretical manuscript, we relate the DFE sampling paradigm to the classical statistical decision theoretic literature and, under a probabilistic inference assumption, evaluate optimal sample sizes for decisions from experience. In our treatment we go beyond analytically established results by showing how the classical statistical decision theoretic framework can be used to derive optimal sample sizes under arbitrary, but numerically evaluable, constraints. Finally, we critically evaluate the value of deriving optimal sample sizes under this framework as testable predictions for the experimental study of sampling behavior in DFE. (shrink)

This study investigated the factorial validity of the 58-item Corporate Ethical Virtues scale :923–947, 2008). The major aim was to test the invariance of the factor structure across different organizational samples. The CEV scale was designed to measure eight corporate virtues: clarity, congruency of supervisors, congruency of senior management, feasibility, supportability, transparency, discussability, and sanctionability. The data consisted of four organizational samples that are operated in the private and public sector. The results of confirmatory factor analyses supported the hypothesized eight-factor (...) structure, as well as its alternative second-order factor structure, where high correlations between the first-order factors were explained by a general CEV factor. These factor structures remained the same across samples, lending strong support for the group invariance assumption of the scale. Thus, the 58-item CEV scale was found to be a valid tool for measuring the aspect of ethical organizational culture in different organizations, and its use can be recommended for future research.

In lieu of an abstract, here is a brief excerpt of the content:Ontological and Other AssumptionsLloyd A. Wells (bio) and Sandra J. Rackley (bio)Fahrenberg and Cheetham have conducted an immensely thought-provoking study of the assumptions about human nature made by 800 students and pose a question about the future impact of these assumptions on individuals’ practice in professions including medicine and psychotherapy.This work represents a branch of “philosophical anthropology,” which considers assumptions people make about human nature. The (...) authors used a questionnaire, much of which was newly designed, to assess the assumptions made by university students studying psychology, philosophy, sciences, and other disciplines. Most of the respondents were studying at Freiburg, but some were sampled at several other universities in both the former East and West Germanies. Questions involved consciousness and the brain, evolution, free will, belief in God, the meaning of life, and theodicy.Given the importance of these beliefs and assumptions in so many peoples’ lives, it is quite surprising that there are so few modern data available, and this study ventures an important first step in assessing these assumptions. However, there are many problems inherent in this study (and any like it).The first, for us, is the validity of the questionnaire itself, an issue that was not specifically addressed in the paper. Face validity is a problem even in the few questions quoted directly in the paper. For example, some statements contain two clauses, and one could well agree with one without agreeing with another: “I do not know whether a God exists and I do not believe it is possible to know.” This is the most relevant answer for a true agnostic, but the assumption that “I do not know whether a God exists” does not necessarily link at all with “I do not believe it is possible to know.” Similarly, a theist might have trouble with the two clauses, “I know God really exists” and “I do not doubt this.” (Technically, knowledge does imply a lack of doubt, but belief certainly does not.) Particularly in the trilemmas, where various patterns of response were analyzed, these multiple-clause statements may have led students to respond in a manner inconsistent with their true beliefs and assumptions. Furthermore, many of the questions contain terms that may have been unfamiliar to first-year university students. The authors explain their rationale in not defining terms, but the lack of clarity about definitions may have led some of the students to not fully understand the questions asked and to perhaps influence the answers they chose.Misunderstanding of the questions may account for some of the disparities reported in the results. Other apparent inconsistencies, however, do not seem to be a result of unclear questions. For example, sixty percent of the students agreed with the statement that “I believe in … existence after death,” whereas forty-seven percent agreed with the statement that “when my brain is dead my consciousness and my person cease to be.” These [End Page 203] findings do not add up, and this study has several similar sets of data. People contradict themselves in long and complex questionnaires, and this may be a simple explanation for these findings, but is this the only explanation? How seriously did the students take the questionnaire, often given as part of their class? How honest were their responses?How generalizable are the findings of this study? It is very difficult even to speculate about this. The statistics are incomprehensible in light of the data given, and one must essentially take them on faith, wherever one falls on the God/theodicy questions. The design has many flaws, but we do learn how a subsample of German university students rate important factors about the meaning of life. Statements are made in the paper that the students’ results correlate with similar results for the general population, but this assertion seems to be based on a very few questions. One would like much more delineation of this apparent correlation, because we wonder about the juxtaposition of developmental factors with the answers the students gave to this questionnaire. First-year university students are at a critical developmental point, and it would be fascinating to follow this large cohort of students over time to see whether... (shrink)

Background Decisions on limiting life-sustaining treatment for patients in the vegetative state (VS) are emotionally and morally challenging. In Germany, doctors have to discuss, together with the legal surrogate (often a family member), whether the proposed treatment is in accordance with the patient's will. However, it is unknown whether family members of the patient in the VS actually base their decisions on the patient's wishes. Objective To examine the role of advance directives, orally expressed wishes, or the presumed will of (...) patients in a VS for family caregivers' decisions on life-sustaining treatment. Methods and sample A qualitative interview study with 14 next of kin of patients in a VS in a long-term care setting was conducted; 13 participants were the patient's legal surrogates. Interviews were analysed according to qualitative content analysis. Results The majority of family caregivers said that they were aware of aforementioned wishes of the patient that could be applied to the VS condition, but did not base their decisions primarily on these wishes. They gave three reasons for this: (a) the expectation of clinical improvement, (b) the caregivers' definition of life-sustaining treatments and (c) the moral obligation not to harm the patient. If the patient's wishes were not known or not revealed, the caregivers interpreted a will to live into the patient's survival and non-verbal behaviour. Conclusions Whether or not prior treatment wishes of patients in a VS are respected depends on their applicability, and also on the medical assumptions and moral attitudes of the surrogates. We recommend repeated communication, support for the caregivers and advance care planning. (shrink)

Cranial electrotherapy stimulation is a neuromodulation tool used for treating several clinical disorders, including insomnia, anxiety, and depression. More recently, a limited number of studies have examined CES for altering affect, physiology, and behavior in healthy, non-clinical samples. The physiological, neurochemical, and metabolic mechanisms underlying CES effects are currently unknown. Computational modeling suggests that electrical current administered with CES at the earlobes can reach cortical and subcortical regions at very low intensities associated with subthreshold neuromodulatory effects, and studies using electroencephalography (...) and functional magnetic resonance imaging show some effects on alpha band EEG activity, and modulation of the default mode network during CES administration. One theory suggests that CES modulates brain stem, limbic, and cortical regions and increases relative parasympathetic to sympathetic drive in the autonomic nervous system. There is no direct evidence supporting this theory, but one of its assumptions is that CES may induce its effects by stimulating afferent projections of the vagus nerve, which provides parasympathetic signals to the cardiorespiratory and digestive systems. In our critical review of studies using CES in clinical and non-clinical populations, we found severe methodological concerns, including potential conflicts of interest, risk of methodological and analytic biases, issues with sham credibility, lack of blinding, and a severe heterogeneity of CES parameters selected and employed across scientists, laboratories, institutions, and studies. These limitations make it difficult to derive consistent or compelling insights from the extant literature, tempering enthusiasm for CES and its potential to alter nervous system activity or behavior in meaningful or reliable ways. The lack of compelling evidence also motivates well-designed and relatively high-powered experiments to assess how CES might modulate the physiological, affective, and cognitive responses to stress. Establishing reliable empirical links between CES administration and human performance is critical for supporting its prospective use during occupational training, operations, or recovery, ensuring reliability and robustness of effects, characterizing if, when, and in whom such effects might arise, and ensuring that any benefits of CES outweigh the risks of adverse events.

In their landmark 2010 paper, “The weirdest people in the world?”, Henrich, Heine, and Norenzayan outlined a serious methodological problem for the psychological and behavioural sciences. Most of the studies produced in the field use people from Western, Educated, Industrialised, Rich and Democratic (WEIRD) societies, yet inferences are often drawn to the species as a whole. In drawing such inferences, researchers implicitly assume that either there is little variation across human populations, or that WEIRD populations are generally representative of the (...) species. Yet neither of these assumptions is justified. In many psychological and behavioural domains, cultural variation begets cognitive variation, and WEIRD samples are recurrently shown to be outliers. In the years since the article was published, attention has focused on the implications this has for research on extant human populations. Here we extend those implications to the study of ancient _H. sapiens_, their hominin forebears, and cousin lineages. We assess a range of characteristic arguments and key studies in the cognitive archaeology literature, identifying issues stemming from the problem of sample diversity. We then look at how worrying the problem is, and consider some conditions under which inferences to ancient populations via cognitive models might be provisionally justified. (shrink)

The article presents an attempt to confirm the circumplex structure of goal contents, identified in 15 cultures around the world, in nine Polish samples. The procedure followed steps from the original study and included testing the assumed 11-factor goal structure and the two-dimensional circular organization of the goal contents. None of the analyses showed outcomes that would explicitly confirm the results attained in the original study. The CFA showed rather poor fits. Results of the MDS generally supported the assumption about (...) the two-dimensional goal contents structure, however ipsative distance analysis reproduced only one of the two assumed dimensions. Finally, although the CIRCUM analysis showed in principle that in the Polish sample the organization of goal contents on the circumference was quite similar to original, the RMSEA indicated poor fit.

The so-called ‘linguistic turn’ that took place in philosophy in the first half of the twentieth century is most strongly associated with the work of Ludwig Wittgenstein. If there is a single text that might be identified as the source of the linguistic turn, then it is Wittgenstein's first book, the Tractatus Logico-Philosophicus, published in German in 1921 and in an English translation in 1922. Throughout his work, Wittgenstein was concerned with the foundations of language; the crucial shift lay from (...) the appeal to simples to the appeal to samples, and a corresponding shift from assumptions about what lies hidden to an appreciation of what is visible to all in our linguistic practices. This article first outlines the main elements of Wittgenstein's early conception of language, before considering his critique of that conception and his later views. (shrink)

Everyday reasoning requires more evidence than raw data alone can provide. We explore the idea that people can go beyond this data by reasoning about how the data was sampled. This idea is investigated through an examination of premise non-monotonicity, in which adding premises to a category-based argument weakens rather than strengthens it. Relevance theories explain this phenomenon in terms of people's sensitivity to the relationships among premise items. We show that a Bayesian model of category-based induction taking premise (...) class='Hi'>sampling assumptions and category similarity into account complements such theories and yields two important predictions: First, that sensitivity to premise relationships can be violated by inducing a weak sampling assumption; and second, that premise monotonicity should be restored as a result. We test these predictions with an experiment that manipulates people's assumptions in this regard, showing that people draw qualitatively different conclusions in each case. (shrink)

The astonishing efficiency and accuracy of DNA replication has long suggested that refined rules enforce a single highly reproducible sequence of molecular events during the process. This view was solidified by early demonstrations that DNA unwinding and synthesis are coupled within a stable molecular factory, known as the replisome, which consists of conserved components that each play unique and complementary roles. However, recent single-molecule observations of replisome dynamics have begun to challenge this view, revealing that replication may not be defined (...) by a uniform sequence of events. Instead, multiple exchange pathways, pauses, and DNA loop types appear to dominate replisome function. These observations suggest we must rethink our fundamental assumptions and acknowledge that each replication cycle may involve sampling of alternative, sometimes parallel, pathways. Here, we review our current mechanistic understanding of DNA replication while highlighting findings that exemplify multi-pathway aspects of replisome function and considering the broader implications. Recent single-molecule studies have revealed that replisome function is dominated by stochastic sampling of multiple molecular pathways. In the context of these new findings, we re-examine the foundational assumptions and seminal experiments that have guided our understanding of replication mechanism and reconcile several long-debated coordination models.

Context can determine whether a given gene acts as an oncogene or a tumor suppressor. Deubiquitinating enzymes (DUBs) regulate the stability of many components of the pathways dictating cell fate so it would be expected that alterations in the levels or activity of these enzymes may have oncogenic or tumor suppressive consequences. In the current review we survey publications reporting that genes encoding DUBs are oncogenes or tumor suppressors. For many DUBs both claims have been made. For such “double agents,” (...) the effects of gain or loss of function will depend on the overall status of a complex of molecular signaling networks subject to extensive crosstalk. As the TGF‐β paradox makes clear context is critical in cell fate decisions, and the disconnect between experimental findings and patient survival outcomes can in part be attributed to disparities between culture conditions and the microenvironment in vivo. Convincing claims for oncogene or tumor suppressor roles require the documentation of gene alterations in patient samples; survival curves are alone inadequate. (shrink)

Scholars have emphasized that decisions about technology can be influenced by philosophy of technology assumptions, and have argued for research that critically questions technological determinist assumptions. Empirical studies of technology management in fields other than K-12 education provided evidence that philosophy of technology assumptions, including technological determinism, can influence the practice of technology leadership. A qualitative study was conducted to a) examine what philosophy of technology assumptions are present in the thinking of K-12 technology leaders, b) (...) investigate how the assumptions may influence technology decision making, and c) explore whether technological determinist assumptions are present. The research design aligned with Corbin and Strauss qualitative data analysis, and employed constant comparative analysis, theoretical sampling, and theoretical saturation of categories. Subjects involved 31 technology directors and instructional technology specialists from Virginia school districts, and data collection involved interviews following a semi-structured protocol, and a written questionnaire with open-ended questions. The study found that three broad philosophy of technology views were widely held by participants, including an instrumental view of technology, technological optimism, and a technological determinist perspective that sees technological change as inevitable. The core category and central phenomenon that emerged was that technology leaders approach technology leadership through a practice of Keep up with technology (or be left behind). The core category had two main properties that are in conflict with each other, pressure to keep up with technology, and the resistance to technological change they encounter in schools. The study found that technology leaders are guided by two main approaches to technology decision making, represented by the categories Educational goals and curriculum should drive technology, and Keep up with Technology (or be left behind). As leaders deal with their perceived experience of the inevitability of technological change, and their concern for preparing students for a technological future, the core category Keep up with technology (or be left behind) is given the greater weight in technology decision making. The researcher recommends that similar qualitative studies be conducted involving technology leaders outside Virginia, and with other types of educators. It is also recommended that data from this or other qualitative studies be used to help develop and validate a quantitative instrument to measure philosophy of technology assumptions, for use in quantitative studies.

Why was Hensen unsuccesful in the quantification of ecological sampling? No aspect of plankton research itself seems to have hindered quantification; both collecting methods and taxonomy were sufficiently advanced. The reason is probably that at the time he began sampling, Hensen had to devise his own statistical methods for expressing the reproducibility and validity of samples. Hensen might have succeeded in this if he had overcome prevalent nineteenth-century attitudes toward randomness.The statistical literature of medicine and physics with which (...) Hensen was probably familiar gave methods for expressing reproducibility and for comparing differences between means of different sets of observations. For example, a student of Poisson writing on medical statistics advocated using Poisson's limit (standard error 2√2) to test the difference between two means56. Other authors suggested that differences between means were most meaningful if very large numbers of observations were used.57 In his laboratory subsampling, Hensen used the propable error as a limit about means. In this and other ways, he seems most indebted to the physicist Ernst Abbe for statistical methods.58 However, all the methodology available to Hensen had been developed for situations in which errors are a property of the measurement or sampling process, and not of the phenomena themselves. The available methods for measuring reproducibility were based on the assumption that differences from the average were small and that they tended to accumulate about the mean in a bell-shaped pattern. Hensen constantly reinvestigated the distribution of plankton numbers about the average using a different method each time. Westergaard points out that medical statisticians did not make such investigations with their biological data.59To a considerable extent, biological sampling problems forced development of theory because samples afforded the only information on a pattern in water or soil which could not be directly observed. The sampling methods of Laplace and the late nineteenth-century government statisticians contrasted strongly with Hensen's because, either through subjective knowledge of the population sampled or through censuses, they attempted to choose representative or typical samples.60 The high reproducibility and validity of representative sampling is attained by knowing more about a population than a biologist can ordinarily know. The uncertain reproducibility and validity of biological sampling spurred the development of formal sampling theory.A formal sampling theory developed only after change in the general intellectual attitude toward randomness, which was reflected in nineteenth-century statistics.61 The ninteenth-century attitude that randomness is not part of nature changed in the twentieth century to a view of randomness as a property of nature.62 The physicist's incorporation of randomness into physical models in response to this intellectual change late in the nineteenth-century is discussed by Bork.63 In biology, the change was initiated by the attention Darwin focused on morphological variation. The English biometricians — Francis Galton and W. F. R. Weldon, for example — were prominent in developing methods for the analysis of biological variation.64 Most pertinent to the development of sampling theory was Karl Pearson's use of frequency distributions as models of biological variation. In ecology, quantification was brought about by Ronald Fisher more than by anyone else; he incorporated randomness into sampling plans and built upon the methods developed earlier for analysis of individual variation. Fisher's use of random sampling allowed comparison between the sample collections and the collections expected from a model population of known patterning (calculated with a frequency distribution). This is a much more efficient method of determining the validity of a sample than Hensen's comparison of collections with a model uniform collection. Intellectual background and accumulated biological information caused Fisher to find variability where Hensen had seen uniformity.In summary, Victor Hensen became interested in fisheries research because of the economic importance of fishing to Germany. Hensen had considerable understanding of the prerequisites for valid sampling, but the value of his quantitative approach was limited by the general preconceptions shared by most nineteenth-century biologists. Through Hensen's efforts many other biologists were stimulated to undertake quantitative samples, even though the statistical methods for analyzing variation among populations developed only after methods for analyzing variation among individuals had been developed. *** DIRECT SUPPORT *** A8402011 00003.

J. Richard Gott III (1993) has used the “Copernican principle” to derive a probability density function for the total longevity of any phenomenon, based solely on the phenomenon’s past longevity. John Leslie (1996) and others have used an apparently similar probabilistic argument, the “Doomsday Argument,” to claim that conventional predictions of longevity must be adjusted, based on Bayes’ Theorem, in favor of shorter longevities. Here I show that Gott’s arguments are flawed and contradictory, but that one of his conclusions—his delta (...) t formula—is mathematically equivalent to Laplace’s famous (and notorious) ‘rule of succession’; moreover, Gott’s delta t formula is a plausible worst-case (if one favors greater longevity) bound in some contexts. On the other hand, the Doomsday Argument is fallacious: the argument’s Bayesian formalism is stated in terms of total duration, but all attempted real-life applications of the argument—with one exception, an application by Gott 1994—actually plug in prior probabilities for future duration; moreover, the Self-Sampling Assumption, an essential premise of the Doomsday Argument, is contradicted by the prior information in all known real-life cases. But rejecting the Doomsday Argument does not entail rejecting the possibility of learning about the future from the past. Applying the work of Bruce M. Hill (1968, 1988, 1993) and Frank P.A. Coolen (1998, 2006) in the field of non-parametric predictive inference, I propose and defend an alternative methodology for quantifying how past longevity of any phenomenon does provide evidence for future longevity. In so doing, I identify an objective standard by which to choose among counting time intervals, counting population, or counting any other measure of past longevity in predicting future longevity. This methodology forms the basis of a calculus of induction. (shrink)

The robustness of the classical tests on means (Z, t, and F) and variances (chi square and F) was investigated by obtaining 30,000 (or, sometimes, 10,000 or 150,000) values of the test statistic under assumption-violating conditions and comparing the actual proportion of Type I errors with the proportion expected when all assumptions are met. The sampling and testing conditions investigated were: population shape (L-shape or bell-shape), relative population variance (1 or 4), sample size (8, 16, or 24), nominal (...) significance level (.05,.01, or.001), and location of rejection region (left-tailed, right-tailed, or two-tailed). All tests on means were nonrobust under most of the investigated conditions, and one was nonrobust under all of them. Both tests on variances were extremely nonrobust under virtually all conditions. The worst nonrobustness of the one- and two-independent-sample Z and t tests rivaled or exceeded that of the notoriously nonrobust chi-square and F tests on variances. (shrink)

Qualitative comparative analysis (QCA) opens up two new forms of knowledge: (1) knowing about alternative pathways to one outcome (equifinality) and (2) perceiving nuances of necessary cause and sufficient cause. Several misunderstandings of QCA occur in the article by Lucas and Szatrowski (this volume, p. 1). First, there are minor problems with expressions. Second, there are differences between their philosophy of science (arguments 1, 2, and 3 below) and a realist approach. Third, they misinterpret what was meant by sufficient and (...) necessary cause (arguments 4 and 5 below). The minor problems with expressions arise in sections 2.2 and 3. In section 2.2, the authors define consistency, but here they miss out on two key points. First, they neglect to say that this particular measure of consistency is a measure of sufficiency of cause, not of necessary cause. Second, they ignore the way that the consistency level exists for each possible configuration of characteristics. A configuration can be shown in one row of a truth table, with n1 = 28, n2 = 17 within a larger sample of 155, and so on (see Byrne 2009:262). Using QCA’s definition of “consistency,” we can discern more about the pattern of causality than one might initially expect. This learning is possible whether N overall is 155, or just 39, or thousands of cases. The essential task is to simplify and rank the list of configurations (Ragin 2001, 2006). (shrink)

Everyday reasoning requires more evidence than raw data alone can provide. We explore the idea that people can go beyond this data by reasoning about how the data was sampled. This idea is investigated through an examination of premise non‐monotonicity, in which adding premises to a category‐based argument weakens rather than strengthens it. Relevance theories explain this phenomenon in terms of people's sensitivity to the relationships among premise items. We show that a Bayesian model of category‐based induction taking premise (...) class='Hi'>sampling assumptions and category similarity into account complements such theories and yields two important predictions: First, that sensitivity to premise relationships can be violated by inducing a weak sampling assumption; and second, that premise monotonicity should be restored as a result. We test these predictions with an experiment that manipulates people's assumptions in this regard, showing that people draw qualitatively different conclusions in each case. (shrink)

The fact that the mystical experience is a repetitive phenomenon in different social, cultural and religious structures in different periods and has a mysterious element in it has caused that mysticism has taken its place among the basic subjects of the field since the first periods of psychology of religion. One of the sections of The Varieties of Religious Experience, which is regarded as the main source of the area, is mysticism. In general, "mystical experience" is considered as a subcategory (...) of "religious experience", which is a wider area. For this reason, it also carries the characteristics of religious experience. Due to these common features, it can be seen that they are used in place of each other in the literature. If the religious experience is defined as the experience of the individual at the time of encounter with the sacred, such experience can be obtained in two ways. In the “religion-based mystical experience”, which is the first way, institutional or established religious thoughts and understandings and holly writings are influential. The second way, “non-religious or natural mystical experience”, can be said to be spiritual quests that individual needs play an important role in them are effective. Personality is used as one of the basic variables in social and health sciences in general, and in psychology because it is among the main subjects in particular. The common emphasis of research on personality is that the phenomenon is extremely complicated. Despite its widespread use, the abstraction of the concept has been influenced by the diversity of the researchers' perspectives and this has led to a lack of clear consensus on the definition. However, in order to investigate the phenomenon in recent periods, dimensional approaches that their basic assumption is personality can be categorized under certain factors have begun to be preferred. In this study, HEXACO was used, because it was thought that it could make a more detailed measurement of personality. The sample of this study is composed of 345 students studying at Erciyes University Theology Faculty in 2017-2018 academic year. When looked at the gender distribution of the sample, the rate of male students was 21.2% (n=73); and the rate of female students was 78.8% (n=272). This reflects the current situation in the faculty. The average age was 21,13 (sd=1,761). The age range is 18-26. Class distribution was 23,5% (n = 81) in Preparatory class; 15.4% (n = 53) in first-grade; 19.4% (n = 67) in second-grade; 18.3% (n=63) in third grade (n = 63); and 23.5% (n = 81) in the fourth grade. It has been noted that distributions are homogeneous in terms of class variables. The "Mystical Experience Scale" which is developed by Ralph W. Hood to measure the criteria which are offered by Walter T. Stace and which must be in the mystical experience has been used in determining the tendency of mystical experience. Hood et al. have reported reasonable reliabilities for subscales based on 3-factor solution. Alpha coefficients of the original scale were ,76, ,69, and ,76 for the extrovertive mysticism, introvertive mysticism and religious interpretation respectively. The adaptation of the scale to Turkish culture and the validity and reliability study were carried out by Mehmet Süheyl Unal as a graduate thesis and it was stated that the Alpha coefficient was ,89. In this study, the Cronbach Alpha reliability coefficient of scale is ,91. HEXACO, developed by Lee and Ashton, was used to determine personality traits. The scale was adapted to Turkish by Wasti, Lee, Ashton and Somer. The scale consists of Honesty-humility (H), Emotionality (E), eXtraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to experience (O) factors. Pearson Moments Multiplication Correlation Analysis was performed to determine if there is a relationship between mystical experience tendencies and personality traits when the data were analyzed in accordance with the aim of the study. Later, it was tried to determine the power of explaining the variables with Multiple Linear Regression Analysis. In addition, One-way ANOVA was used to determine whether there was any relationship between significance levels. Moreover, descriptive statistics of relevant variables are included in the study. Findings show that participants have the highest average to Positive Affect (m=3,69; sd.=,77) and the lowest average to Temporal/Spatial Quality (m=2,94; sd.=,89) factor in terms of mystical experience. Additively, they obtained close values in Ego Quality, Noetic Quality and Ineffability factors. When the students were evaluated in terms of gender, it was seen that there was a difference in level of significance only in terms of Unifying Quality (t=1,770; p=,028). ANOVA analysis was carried out to determine whether there was any variation in class variable. As a result of this analysis, it is seen that all of the factors are significantly differentiated in terms of class variable. From the standing point of class variable, it is seen that the first grades differed negatively compared to the other classes. According to the data, the scores on the mystical experience scale for preparation and first grade are high while the averages for the next grade are falling. There is no difference on level of significance between age and mystical experience factors, the last independent variable. When looked at the correlations among mystical experience factors, it is understood that all of the factors are in a meaningful relationship with each other. The highest correlation is between Religious Quality and Ineffability (r=,661); the lowest correlation is between the Unifying Quality and the Temporal/Spatial Quality (r=,346). Among the six factors of HEXACO that have been developed to determine the personality traits, the students have the highest average on Humility-Honesty (m=3,76; sd.=,55); the lowest average on eXtraversion (m=3,04; sd.=0,65). In terms of gender, there is a statistically significant difference in factors of Humility-Honesty (t=,606; p=,004), Emotionality (t=,334; p=,000), and Constientiousness (t=,022; p=,033). There is no significant difference between class and age variables and personality traits. According to Linear Regression analysis, Agreeableness, Constientiousness and Openness to Experience factors of personality traits are predictive of mystical experience in a significant level statistically. Personality dimensions that are most related to mystical experience as a result of analysis are Conscientiousness and Openness to Experience. When the mystical experience is compared with the personality traits, it is concluded that Openness to Experience factor is related to all the factors of the mystical experience except for the Ineffability. Although the relationship is regarded as weak in terms of correlation, it is an important finding that there are positive relations in between. In other words, as personality traits evolve, the mystical experience level also increases. The lack of a similar work in the literature in this respect removes the possibility of making comparisons.

The author analyses the reliability and accuracy of the results of sociological research conducted using quota sampling. The author discusses the advantages and disadvantages of using quota samples compared to random samples. The main focus is on the representativeness of the obtained data and the possibility of extrapolating them to the general population.In the problem statement, the author noted that a mechanical method of forming a random sample is most often used to study public opinion in Ukraine. The main (...) feature of this method is to ensure an equal probability of selection of each element of the general population. The author emphasizes that although this method allows for easy calculation of possible errors and analysis of collected information, it has a disadvantage in representing specific groups of the population.To address this problem, the author proposes using an equal probability method of forming quota samples, which allows selecting respondents according to their quotas in the general population, thus providing a more representative model of the studied population. However, in the scientific community, there is no consensus on the use of indicators in forming quota samples, and all existing works remain at the level of theoretical assumptions.The author attempts to empirically substantiate the effectiveness of quota samples through experimentation. The hypothesis of the experiment assumes that the results of studies conducted according to quotas can be extrapolated to the general population with high accuracy and reliability using mathematical and statistical methods. During the experiment, both quota and random samples were used to compare the results.The general population consisted of 489 musical compositions represented in different proportions to eliminate the subjective component from the experiment and provide the opportunity to clearly assess and record the parameters of the initial general population for further comparison with the results of different types of samples. The musical compositions had two parameters: the name of the performer for identification and the duration of the track for digital and statistical evaluation. The analysis was carried out using a specially developed program for statistical data analysis. The collected data allowed for the assessment of the average track duration, median, skewness, standard deviation, and other statistical indicators.The results of the experiment showed that the quota sample provides more accurate results when the quotas are followed during the selection of elements of the general population. The sample obtained by random selection without adhering to quotas showed greater variability in indicators such as mean, median, skewness, and standard deviation relative to the general population. Thus, it was concluded that quota samples have advantages in sociological research, especially when specific groups of the population need to be considered.The author emphasizes the need for further research and improvement of quota sampling methods to enhance the accuracy and reliability of sociological studies, which are important for examining particular social issues.

BackgroundStress is a major risk factor for the impairment of psychological well-being. The present study aimed to evaluate the empirical evidence of the Transactional Stress Model proposed by Lazarus and Folkman in patients with psychosomatic health conditions.MethodsA structural equation model was applied in two separate subsamples of inpatients from the Department of Psychosomatic Medicine for consecutive model building and confirmatory analyses using self-reported health status information about perceived stress, personal resources, coping mechanisms, stress response, and psychological well-being.ResultsThe initial model was (...) created to reflect the theoretical assumptions by Lazarus and Folkman about their transactional stress concept. This model was modified until a sufficient model fit was reached. The modified model was confirmed in a second sample. Perceived external stressors and personal resources explained 91% of the variance of the stress response, which was closely related to symptoms of depression. The attenuating effect of resources on stress response was higher than the impact of perceived stressors on stress response.ConclusionThe empirical data largely confirmed the theoretical assumption of the Transactional Stress Model, which was first presented by Lazarus and Folkman, in patients with a wide range of psychosomatic conditions. However, data analyses were solely based on self-reported health status. Thus, proposed inner psychological mechanisms such as the appraisal process could not be included in this empirical validation. The operationalization and understanding of coping processes should be further improved. (shrink)

The Doomsday argument purports to show that the risk of the human species going extinct soon has been systematically underestimated. This argument has something in common with controversial forms of reasoning in other areas, including: game theoretic problems with imperfect recall, the methodology of cosmology, the epistemology of indexical belief, and the debate over so-called fine-tuning arguments for the design hypothesis. The common denominator is a certain premiss: the Self-Sampling Assumption. We present two strands of argument in favor of (...) this assumption. Through a series of thought experiments we then investigate some bizarre prima facie consequences – backward causation, psychic powers, and an apparent conflict with the Principal Principle.

I discuss two versions of the doomsday argument. According to ``Gott's Line'',the fact that the human race has existed for 200,000 years licences the predictionthat it will last between 5100 and 7.8 million more years. According to ``Leslie'sWedge'', the fact that I currently exist is evidence that increases the plausibilityof the hypothesis that the human race will come to an end sooner rather than later.Both arguments rest on substantive assumptions about the sampling process thatunderlies our observations. These (...) class='Hi'>sampling assumptions have testable consequences,and so the sampling assumptions themselves must be regarded as empirical claims.The result of testing some of these consequences is that both doomsday argumentsare empirically disconfirmed. (shrink)

A probabilistic logic of induction is unable to separate cleanly neutral support from disfavoring evidence (or ignorance from disbelief). Thus, the use of probabilistic representations may introduce spurious results stemming from its expressive inadequacy. That such spurious results arise in the Bayesian “doomsday argument” is shown by a reanalysis that employs fragments of an inductive logic able to represent evidential neutrality. Further, the improper introduction of inductive probabilities is illustrated with the “self-sampling assumption.”.

A sample of college women and men responded to a survey assessing attitudes, beliefs, experiences, and behaviors relevant to sexual harassment and assault. Men were more tolerant of sexual harassment, more likely to believe that heterosexual relationships were adversarial, more likely to subscribe to rape myths, and more likely to admit that they might sexually assault someone under some circumstances. Data from the present study support the proposition that relevant affective, cognitive, and behavioral indices of hostile sexuality directed against women (...) are linked, supporting the assumption of a continuum of misogyny. Significant positive correlations were predicted and found among men's self-reported tolerance for sexual harassment, adversarial sexual beliefs, rape-myth acceptance, likelihood to rape, and experience as a sexual victimizer. Among women, belief and attitude measures were positively correlated but, as predicted, experience of sexual victimization was not reliably related to any other measure, supporting the conclusion that personal characteristics are not relevant to college women's sexual victimization.

In this paper I provide a frequentist philosophical-methodological solution for the stopping rule problem presented by Lindley & Phillips in 1976, which is settled in the ecological realm of testing koalas’ sex ratio. I deliver criteria for discerning a stopping rule, an evidence and a model that are epistemically more appropriate for testing the hypothesis of the case studied, by appealing to physical notion of probability and by analyzing the content of possible formulations of evidence, assumptions of models and (...) meaning of the ecological hypothesis. First, I show the difference in the evidence taken into account in different frequentist sampling procedures presented in the problem. Next, I discuss the inapplicability of the Carnapian principle of total evidence in deciding which formulation of evidence associated with a given sampling procedure and statistical model is epistemically more appropriate for testing the hypothesis in question. Then I propose a double-perspective (evidence and model) frequentist solution based on the choice of evidence which better corresponds to the investigated ecological hypothesis, as well as on the choice of a model that embraces less unrealistic ontological assumptions. Finally, I discuss two perspectives of the stopping rule dependence. (shrink)

Most models of response time (RT) in elementary cognitive tasks implicitly assume that the speed-accuracy trade-off is continuous: When payoffs or instructions gradually increase the level of speed stress, people are assumed to gradually sacrifice response accuracy in exchange for gradual increases in response speed. This trade-off presumably operates over the entire range from accurate but slow responding to fast but chance-level responding (i.e., guessing). In this article, we challenge the assumption of continuity and propose a phase transition model for (...) RTs and accuracy. Analogous to the fast guess model (Ollman, 1966), our model postulates two modes of processing: a guess mode and a stimulus-controlled mode. From catastrophe theory, we derive two important predictions that allow us to test our model against the fast guess model and against the popular class of sequential sampling models. The first prediction—hysteresis in the transitions between guessing and stimulus-controlled behavior—was confirmed in an experiment that gradually changed the reward for speed versus accuracy. The second prediction—bimodal RT distributions—was confirmed in an experiment that required participants to respond in a way that is intermediate between guessing and accurate responding. (shrink)

For a sample comprising 36,105 U.S. firm-year observations from 1985 to 2008, we find that firms located in more religious counties enjoy cheaper equity financing costs. This result is robust to a battery of sensitivity tests, including alternative assumptions and model specifications, additional controls for noise in analyst forecasts, and various approaches to addressing endogeneity. In another set of tests, we find that the equity pricing role that religion plays comes predominantly from Mainline Protestants. We also document that the (...) effect of religiosity on firms’ cost of equity capital is larger for firms (periods) lacking alternative monitoring (regulation) mechanisms as measured by lower institutional ownership (the pre-SOX era), implying that religion plays a corporate governance role. Finally, we find that the importance of religion to equity pricing is concentrated in firms that suffer lower visibility, which tend to be more sensitive to local social and economic factors. By examining the links between religiosity and valuation at the firm level, we provide strong, robust evidence supporting the perspective that religion facilitates economic development. (shrink)

Using the assumptions of Sternberg Duplex Theory of Hate, the present study reveals the combined effects of similar competitor offer and narcissistic personality on brand equity through the underlying mechanism of brand hate. Specifically, we hypothesize that brand hate mediates the relationship between similar competitor offer and brand equity. Moreover, we propose that similar competitor offer and brand hate relationship are stronger for narcissistic individuals. By employing a multi-wave time-lagged research design, we collected data from a sample of dairy (...) product consumers in Pakistan. The findings of moderated-mediation regression analyses indicate that Brand hate mediates the relationship between similar competitor offer and brand equity; and Narcissistic personality moderates a similar competitor offer and brand hate relationship such that a high similar competitor offer led to greater brand hate when narcissism was high. Furthermore, conditional indirect effects reveal that brand hate mediates the relationship between similar competitor offer and brand equity only with individuals exhibiting narcissistic personality traits. The current study offers great insights to managers that by managing similar competitor offer, they can manage the development of brand hate, which can subsequently effect brand equity. Moreover, by profiling customers on the basis of their personalities, marketing managers can effectively invest only in customers with positive tendencies. The current study is unique in that it highlights new avenues in existing research by extending the nascent domain of brand hate in consumer–brand relationships. (shrink)

The present studies tested the hypothesis that strong assumptions about within-category homogeneity impede children’s recognition of the inductive value of diverse samples of evidence. In Study 1a, children (7-year-olds) and adults were randomly assigned to receive a prime emphasizing within-category variability, a prime emphasizing within-category similarities, or to not receive a prime. Only following the variability prime, children demonstrated a reliable preference for evaluating diverse over nondiverse samples to determine whether there is support for a category-wide generalization. Adults demonstrated (...) a robust preference for diverse samples in all conditions. These effects extended beyond the specific categories included in the prime, as well as to multiple types of test questions. Study 1b demonstrated that priming variability leads children to select diverse samples only when doing so is informative for induction. Implications for conceptual development are discussed.

Based on the assumption that consumers will reward firms for their support of social programs, many organizations have adopted corporate social responsibility (CSR) practices. Drawing on social identity theory, a model of influence of CSR on loyalty is developed and tested using a sample of real consumers. Results demonstrate that CSR initiatives are linked to stronger loyalty both because the consumer develops a more positive company evaluation, and because one identifies more strongly with the company. Moreover, identity salience is shown (...) to play a crucial role in the influence of CSR initiatives on consumer loyalty when this influence occurs through consumer-company identification. A strong identifier is not necessarily in a constant state of salience, but activating identity salience of a particular consumer social identity (a company) will affect consumer reactions to product stimuli, increasing consumer loyalty.

The assumption that the onset of puberty is a context-sensitive marker of a reproductive strategy is tested by comparing parental and filial childhood context and somatic development in West and East Germany. Sixty-eight mother-daughter dyads and 35 father-son dyads were taken from two samples of families from Osnabrück in West Germany and Halle in East Germany. According to the observed context discontinuity between the generations in the male dyads, linear regression models show that no indicator of male sexual maturation was (...) influenced significantly by the somatic development of the father. Instead of an inherited timing of maturation, antecedent distal factors like socioeconomic childhood context variables and critical life events lead to an acceleration of male sexual maturation. Finally we test the effect of two different conditions of childhood context continuity on daughter’s age at menarche with maternal age at menarche controlled. Linear regression models show that mother’s age at menarche predicts daughter’s age at menarche only under the condition of contextual continuity between generations, which was the case in the West German sample only. In East Germany, where mother’s age at menarche had no significant effect, the amount of variance explained by childhood context variables was almost the same. These results indicate the context sensitivity of somatic development which seems to follow an evolutionary rationale. (shrink)

The movement called Experimental Philosophy (‘x-Phi’) has now passed its tenth anniversary. Its central insight is compelling: When an argument hinges on accepting certain ‘facts’ about human perception, knowledge, or judging, the evoking of relevant intuitions by thought experiments is intended to make those facts seem obvious. But these intuitions may not be shared universally. Experimentalists propose testing claims that traditionally were intuition-based using real experiments, with real samples. Demanding that empirical claims be empirically supported is certainly reasonable; though experiments (...) are not necessarily the only means available. When experiments are conducted, adequately interpreting their results requires understanding the study’s design (and possibly flaws) that produced them. Experiment-based reports should document the design clearly. If Plato, writing his Meno, replaced accounts of Socrates demonstrating geometry to a slave-boy, with a survey of 100 real boys—some grasping his demonstrations, others not—what conclusions could be reached? Before answering, the reader needs details on key design questions, including (among others): (a) What population are these samples intended to represent? (E.g., ‘all slave boys’?; ‘math-ignorant people’?; ‘everyone’?) (b) What statistical tests were conducted, on what assumptions? (c) How was ‘significance’ of results determined? (d) Was the test instrument’s validity established? For readers wishing to explore x-Phi’s potentials, as contributors or as interpreters of their findings, this paper offers some cautionary considerations. Throughout their literature, examples can be found casting doubt on some experimentalists’ findings, due to design-related issues. Increased awareness of methodological questions would tighten the x-phi literature, going forward . (shrink)
